  • Russia wants to reduce the export tax on crude oil and petroleum products to zero.

    The Russian government passed the decree twice successively in July and August 2018 to reform the taxes of its domestic oil industry. The general principle is to reduce the export tax on crude oil and petroleum products until to zero, and increase the oil exploitation tax in equal amounts. Although this tax reform will increase the price of domestic refined oil products in Russia in the short term, and the new tax refund system and dumping factor will make its oil tax system more complicated, in the long run, the new tax system will help increase government revenue and the competitiveness of Russian oil in the international market, can also promote the upgrading of its domestic refining industry, which does more good than harm to both the Russian government and the oil industry.


     
    I. Eliminating export tariffs is not on the spur of the moment.
     
    II. The tax reform is strong.
     
    III. The positive impacts far exceed the negative ones.
    (1) The new tax system increases government revenue while reducing the financial burden.
    (2) It will increase the competitiveness of Russian oil, oil products and related companies.
    (3) It can offset the tax losses of Russian oil exports caused by the low tariffs of the Eurasian Economic Union.
     

    Without doubt, this reform has adverse impacts on Russia too. On the one hand, this tax reform introduced many new calculation formulas and tax measures, making the tax system of the Russian oil industry more complicated. On the other hand, Russian new oil tax system has an obvious "self-interest" color, which may affect Russia's relations with its some trading partners, especially Belarus, Kazakhstan, etc., and will increase the probability of local divergences of oil import and export.

  • Analysis of Resource Utilization of Sludge

    KOSUN is a professional company that provides solid-liquid separation products and integrated solutions to solid waste disposal in the fields of energy conservation and environment protection, and focuses on development and services of complete technologies and equipment in sludge reduction, harmlessness and resource utilization. The sludge treated by KOSUN vertical centrifuge can be used as various resources in the following fields:
     

    1. Agricultural resource utilization of sludge
    If the sludge is used for agricultural purposes, it has the advantages of low operating cost, low energy consumption and low investment, and the organic part in sludge can be converted into the modifier component in the soil, so this utilization way is taken as the most promising disposal method.
     
    2. Building materials utilization of sludge
     
    2.1. Cementitious materials utilization of sludge
    For sludge, it often contains more ash, especially in the treatment of sludge in wastewater by coagulation method, which contains a lot of Fe and Al components, and can be used as additives of building materials.
     
    2.2. Sludge ceramsite
    For lightweight ceramsite, it is usually used as a flower covering material or as a concrete aggregate and roadbed.
     
    2.3. Sludge brick
    Relevant researches show that sewer sludge can be used to make ecological bricks used in construction. This kind of brick is actually made by the following process: 10% sludge is mixed into the clay and then fired at 900°C, which can optimize the effect.
     

    3. Animal feed utilization of sludge
     
    Sludge contains lots of corresponding substances with many useful values, such as ash content ratio of 26.1% to 46.3%, fatty acids of 0 to 3.5%, and crude protein of 28.4% to 40.8%. Therefore, it can be treated as feed protein.
     
    4. Sludge as fuel
     
    The sludge itself is rich in organic matter. After low-temperature carbonization of sludge, the calorific value is equivalent to lignite, so the sludge can be used as fuel with a low calorific value.
     
    If the sludge is not treated and is directly discharged into the environment, it will be seriously harmful to the surrounding environment. After the sludge is treated harmlessly, stabilized and reduced in volume, it can be used as a valuable resource in many fields.

  • IEA: An acute shortage of global fuel oil supply will continue in next two years

            The International Energy Agency (IEA) estimates that fuel oil supply is expected to face an acute shortage before 2020 when sulfur limit for marine fuel is set due to upgrade in refinery and a decline in medium and heavy crude oil production. According to the new regulations of the International Maritime Organization (IMO), by January 2020, the highest proportion of marine fuel sulfur will be reduced from the current 3.5% to 0.5%.

           The IEA says, since November last year, due to the OPEC and non-OPEC (such as Russia) production reductions, the global production of medium and heavy crude oil has dropped by 1.4 million barrels per day, reducing the residual fuel oil market by 500,000 barrels per day. In the fourth quarter of last year, global demand for residual fuel oil was 6.74 million barrels per day, declining by 2.2% year-on-year.

            The IEA states that the reduction in global crude oil supply is narrowing the profit margin of complex refineries comparing with simpler ones, which in turn leads to the disappearance of advantages of complex refineries. The increasing strengthening of fuel oil cracking in the past five months has made upgrades less feasible.

  • What is the Functions of a Drilling Fluid?

    Mud is the common name for drilling fluid.  While it is outside the scope of this handbook to offer a detailed discussion of drilling fluids, a brief outline of the general characteristics of drilling fluids is included to establish the basic relationships between drilling mud and solids control.  Similarly, any discussion of solids control would be incomplete without establishing an understanding of the nature of mud solids — their size, shape and composition.


    Functions of a Drilling Fluid:
    The mud system in a drilling operation performs many important functions. These include:

    -Clean beneath the bit: To maximize drilling efficiency, the drilling fluid must translate hydraulic horsepower from the main mud pumps into enough velocity to remove drill cuttings away from the face of the bit and allow the cutters to be in contact with the formation. If the cuttings are not removed, they will be ground into smaller particles and adversely affect drilling rate, mud properties, and project costs.

    -Carry drilled solids from the bottom of the hole to the surface: Once cuttings are removed from beneath the bit, the fluid must transport them toward the surface faster than they can settle back toward the bottom of the hole.  Factors which influence cuttings movement are velocity, cuttings size and shape, and the fluid properties.

    -Suspend cuttings when circulation is stopped: Circulation of the drilling fluid stops periodically during operations, such as when making a bit trip.  The drilling fluids must be able to suspend cuttings and weighting material while circulation is stopped, but should begin to flow easily when the pumps are switched back on.  Properties which affect cuttings suspension are the density and viscosity of the mud and the density of the solids in the mud.

    -Allow removal of cuttings by the surface system.
    -Control formation pressures.
    -Promote borehole stability.
    -Cool the bit and lubricate the drill string.
    -Help support the weight of the drill string.
    -Allow accurate information from the well. 

  • The Classification and Working Principle of Shale Shaker

    Shale Shaker is a vibration screening machinery used for treating refractory materials. The shale shaker has the process characteristics of large amplitude, high vibration intensity, lower frequency and flexible screen surface. During the work process, shale shaker always maintain the largest open-hole rate with high screening efficiency, processing capacity, easy to replace sieve, reducing costs. Shale shaker large screen surface and large processing capacity can meet the production needs of the scene.

    The Classification of Shale Shaker
    – According to use, shale shaker can be divided into mining shaker, light fine shaker, Vibrating shaker.
    -Mine shaker can be divided into: high-efficiency heavy-duty shaker, self-center shaker, elliptical shaker, dehydration shaker, round vibrating shaker, banana shaker, linear vibrating shaker.
    -Light fine shaker can be divided into: vibrating shaker, linear shaker, vertical shaker, ultrasonic vibrating shaker, filter shaker.
    -According to the material running track, shale shaker can be divided into: linear vibrating shaker and circular vibrating shaker.
     
    Working Principle of Shale Shaker
    When the shale shaker is working, the two synchronous motor reverse rotation so that the exciter produce reverse excitation force, forcing the sieve mesh sieve to do longitudinal movement, so that the material on the subject by the exciting force and periodically throw forward a range to complete the material screening operations. Shale shaker is suitable for screening quarry stone, also for coal preparation, mineral processing, building materials, electricity and chemical industries for product classification.
     
    Shale shaker working part is not moving, by sliding along the face of the material so that the material is screened. Fixed grid sieve is more commonly used in the concentrator, generally used for pre-screening coarse or broken before. It is simple in structure and easy to manufacture.
     
    Shale shaker working face is composed of a horizontal scroll shaft, the plate has a shaft, the fine material from the gap between the roller or plate through. Large pieces of material driven by the roller to move one end and discharged from the end. Working part of the shaker cylindrical, the sieve around the cylinder axis rotation, the axis installed in general tilt. Material is fed from one end of the cylinder, fine-grained material passes through the mesh openings in the cylindrical work surface and coarse material is discharged from the other end of the cylinder. 

  • Hydrocyclones Main Parameters

    There are many parameters associated with hydrocyclones, such as structural aspects, process operations, and feedstock properties. The following is a brief description of the main parameters of hydrocyclone:

    (1) Cylindrical cylinder diameter and height. The diameter is the main size of the hydrocyclone, it has a certain relationship with the size of other components. If increasing this diameter size, the throughput will increase, but the overflow particle size will become thicker. In order to classify the fine-grained material and increase the throughput, it commonly uses a large number of small-sized cyclones in parallel. The height of the cylindrical body is generally 0.6 to 1.0 of its diameter.


    Hydrocyclones

    (2) Inlet diameter of the mine. This diameter is usually 0.08 ~ 0.25 of the diameter of the hydrocyclone. A value larger than this would increase the throughput, but the classification efficiency is reduced. The inlet diameter of the mine is often made of rectangular.

    (3) Overflow pipe diameter. This diameter is generally 0.1 ~ 0.4 of the cyclone diameter, which can be used to adjust the relative yield of overflow and grit. The diameter of the overflow pipe increases, the overflow increases, the overflow particle size becomes thicker, the fine sand decreases and the concentration increases.

    (4) Output diameter of the sand. Normally, output diameter of the sand increases, the overflow volume decreases, the overflow grit size decreases, and the grit amount increases, the concentration becomes lower and the grit size increases, but it has no obvious effect on the processing capacity.

    (5) Overflow pipe insertion depth. Too shallow insertion can cause the coarse particles entering  the overflow. Inserting too deeply cause the bottom coarse particles entering into the overflow, which will reduce the classification efficiency. The depth of the overflow pipe should generally be 0.7-0.8 of the height of the cylindrical cylinder.

    (6) Conical cylinder cone angle. Increasing the cone angle reduces the height of the equipment and increases the average radial velocity of the slurry.

    (7) Ore feeding pressure. Commonly ore pressure is 49 ~ 157kPa (0.5 ~ 1.6kgf / cm2). There is a direct relationship between pressure and processing capacity and particle size separation. Increasing the pressure to the ore reduces the graded size and increases throughput.

    (8) Pulp properties. Mainly refers to the ore density, particle size and pulp concentration. The appropriate pulp concentration is usually determined experimentally on a case by case basis. (Editor:Kosun Lily.Wang)

  • Several ways to install Linear Motion Drying Shaker Vibration Motor

    Linear Motion Drying Shaker is a common vibration screening equipment. It is widely used in various sectors of the material screening and classification workflow. Linear Motion Drying Shaker applied to chemical industry, food, plastics, medicine, metallurgy, glass, building materials, food, fertilizer, abrasive, ceramics and other industries.


    linear motion drying shaker

    Linear Motion Drying Shaker is mainly composed of screen box, screen frame, screen, vibration motor, motor base, damping spring, bracket and other components. According to customer's site size and different materials, Vibration motor installation methods are usually the following three common installation:

    1, vibration motor installed at the bottom of linear motion drying shaker
    This is the most common way to install a Vibration motor. Customers are usually advised to choose this type of installation, which is safe, reliable and space-saving. If the customer's site width is limited, the site should be placed in addition to the linear sieve equipment, the two sides of the linear sieve should also leave a certain width, which would be convenient for feeding,  maintenance and other operations.

    2, vibration motor installed on both sides of the linear motion drying shaler
    This installation is also a common installation method for linear motion drying shaker vibration motor. It is usually used when the customer has a limit on the overall height of the equipment, and there is no limit to the width of the equipment. As the special requirements of some materials, equipment outlet can not be too high from the ground. This method not only satisfies the customer's requirement for the height of the linear shaker, but also not affect the work efficiency of the equipment.

    3, vibration motor installed in the top of the linear motion drying shaker
    This installation method has very few customers to choose, if the customer has the limit of the height and width of linear shaker equipment discharge port, you can installed the vibration motor in the middle of the top of the device. Using this method,it can neither increase the width of the device, nor affect the height of the device discharge port.

    The above three methods of vibration motor installation are the commonly installation methods used in linear motion drying shaker. The users can choose them according to their actual situation. (Editor:Kosun Lily.Wang)
